One of the reasons it's bad.
i've always liked this movie even though I know it isn't a good movie.
Parts of the movie works, the other part doesn't. I think the part of the movie that really doesn't work is the whole play within a play itself. "English with Tears" is just bad. Which is odd. The screenwriter is an actual playwright so it's odd that he didn't put more into the actual play within the movie. As a result, none of the scenes involving the actual play seem to work. Even Dyan Cannon isn't really that great. I think there is always a big problem when you do a movie ABOUT an entertainment occupation (dance, plays, movies, comics, writing, etc). If you show the actual work within, it HAS to be good otherwise some of the movie's entire credibility is shot. If Ivan is such a great playwright, let's write a good play for him, otherwise don't show any of it.
I do like Alan King and Bob Dishy as the producer and director but they could have easily made this movie making Ivan a different profession and it would have been better...because the scenes that work are ALL about Ivan and his kids.
(and some of the fights with Gloria)
